To all whont it WI/(11y concern:

,Be it known that I, LOUIS LABADIE D uecs, a citizen of the UnitedStates, residing at Washington, District of Columbia, have in ventedcertain new and useful Improvements in Gun-Mounts; and I do herebydeclarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My present invention relates to improvements in gun-mounts, and it ismore especially intended to provide means whereby the gun may bequicklyv and accurately pointed.

The improved means for pointing the gun comprises mechanism foradjusting the gun in elevation while the line of sight iskept on thetarget, thus regulating the adjustment between the line of sight and theline of fire without taking the sight or sights off the target, and alsoin improved means whereby the un may be trained either from theshoulderbar or by power-gearing, as may be desired.

My invention also consists in certain novel constructions, combinations,and arrangements of parts, as will be hereinafter more fully describedand claimed.

Reference is had to the accompanying drawings, in which the same partsare indicated by the same letters throughout the several views. I

Figure 1 shows a side elevation of the gun and mount and shows theelevatinggear and sighting-arm with connected parts. Fig. 2 is a planview of the gun and mount.

Figs. 4 and 5 are detail views showing thetraining-gear on a largerscale, Fig. 5 being a section on the line 5 5 of Fig. 4 and lookingdown. Fig. 6 is a detail view, on a smaller scale, taken along the line6 6 of Fig. 5 and looking in the direction of the arrows. Fig. 7 is adetail view showing parts of the elevating-gear and the sightingmechanism on an enlarged scale; and Fig.8 represents a section of theparts mounted on the main elevating-shaft, the said section being alongthe line 8 8 of Fig. 7 and looking in the direction of the arrows.

A represents the gun, which is mounted to recoil in the rocking slide Bagainst the resistance of the recoil-cylinders B. This slide Fig. 3 isriage C, which top carriage is turned on the bottom carriage C" intraining the gun. The top carriage has a rearwardlyprojecting Web C",carrying the brackets C and G I D represents the sighting-arm, which ispivoted on one of the trunnions B and is curved upward to carry asuitable sight:- such, for instance, as the telescope D. Thissighting-arm is provided with an index (1", which points to a graduatedscale b on the web B which projects rearward from'the slide 13. This webalso carries a curved rack 12. (See Figs. 1 and 7.) The sightin-armD hasa downwardly-projecting curve rack cl secured thereto, which rack meshesin the pinion c on the shaft E, which shaft carries a worm-gear E, whichmeshes with the Worm F, fast on the shaft F. This shaft F has looselymounted thereon the sleeve F carrying at one end the hand-Wheel F forturning said sleeve and provided at the other end with an annular rib fto en age the clutch member F which is normally pressed into engagementwith the clutch member F' 'by means of the spring F The clutch member Fis fast to the sleeve F and the clutch member F is fast to the shaft F,the shaft being journaled in the bracket C and the sleeve F beingjournaled in the bracket C The end of the shaft F is provided with ahead f to limit the longitudinal motion of the sleeve thereon, andsuitable antifrictionbearings f are provided Where desired. It will beseen from an inspection of Fi 8 that the spring F will normally tend toold the clutch members F and F in frictional engagement, in which caseif the hand-wheel F be turned both the sleeve F and the shaft F will beturned with it, while if the hand-wheel be drawn out slightly againstthe action of the spring F releasing the frictional engagement of theclutch members F and F", the

sleeve F may'be turned freely on the shaft F without turning said shaft.

Splined on the sleeve F? is a worm F7, which meshes in the worm-gear Hon the shaft H, journaled in the bracket 0 which shaft carries on itsinner end the gear-Wheel Hiwhich meshes with the curved rack b, fast tothe vertical web B which is secured to or integral with the slide B.Thus'it will be seen the t if the henzhwheel F" be turned the gear-Whcel 5" will cause the reek turning-of the hend-wheel F will merelyelevote and depress the gun without i-lfecting the position of thesighting-arm; hut when these clutch members are in engagement turningthe hand-wheel F" will not only elevate or depress the gun, hut willalso impart a. corresponding motion to the sighting-arm D by means ol.its rack (Z and the gearing connecting said ruck with the shaft F.

In practice the sight is first brought to bear on the targetirrespective of the elevation at which the gun is to he fired. Thenkeeping the sight on the target, the hand-Wheel F" is drawn back,releasing the clutch Inemhers F and F and the gun is elevated ordepressed until the pointer d" on the sightingerin points to the properelevation on the scale t (See Fig. 1.) Now if the sight is still on thetarget the gun will he properly pointed. Now the hand-wheel released andthe sleeve F is allowed to press l'orvmrd under the action .of thespring 5", causing the clutch members F end F to engage, and both gunand s1ght= may he rocked in unison about the trunnions B by turnii'igthe linnd-wl1e0l F The worms and gear for operating the two racks b and(Z are preferably so proportioned that both the sleeve and sighting-emu.will he rocked through an equal angle, no matter What may he the motionof the luuuhwheel F, and thus the relative bearing between the line ofsight and the line of lire will be maintained constant, except, oicourse, for the slight difference due to setting the sight at en angleto compensate for dril't, &c. This, however, is a feature Well known'inthe art and need not he further considered in this specification.

Thus it will he seen that I pro ide means h Y hich the. desired anglebetween the line of sight end line oi lire inaybequiuhly and seourntel varrived at without requiring ill? gun-pointer to hike his sight oi? oithe target, and as the gun is further elevated or dopressed incident topointing this angle between the line of sight and the line ol lire willhe maintained. This is oi special importance in the l in the method ofsighting guns now most commonly in use when it desired to change the ole.ition ol' the gun it is the practice to reset the rear sight and thento try to find the target by elevating or depressing the gun; but will]the lieroin-doscrihed mechanism the sight is first brought on the targetand then is kept there while the line of lire of the gun is brought intoproper relation. with the line of sight. In [his wily no time is lost inpicking up the target and greater rapidity and accuracy of lireurcolituinzthie.

F r convenience in operating the gun the l gun-winter is provided with eshoulder-rest I, z nched to the verticully-edjustehle her i, which isclamped at the desired height in the socket I by nieansof the clamp Thissocket I is detechuhly connected to ,the arm C", secured to the topcarriage C.

The herein-described device for elevating and depressing the gun isintended to operate in training from the shoulder independently of or inconnection with the traininggear that will now be described.

T he training-gear proper is preferably on the opposite side of the gunfrom the shoulderdmr and elevating-gear and is operated by anothermember of the guns crew, under the direction, of course, of thegun-pointer.

K represents a pinion meshing in a circuler reek C (see Fig. 8 and indotted lines in Fig. 2,) his: on the lower carriage C. This pinion islast on the shaft K, journuled in the )racket fast to the upper carriageC. This shaft K has n worm-gem if? loosely mounted on the some near itsupncr end, which gear is caused to turn no mal with said.

shaft 0} means oi tlzv 'irietio'wd 1'5 (See Fig. 4.) The purpose of ticl'ionul engegeinent is to prevent the sripping of teeth or injurx toother parts of the training-gear when excessive st sins are imposedthereon. This wornrgeur it! meshes with the worm hi on the shaft M,whioh shaft Curries the bevelgear M", meshing with the pinion N on theshaft N, which shuit carries the hand-Wheel N and is journeled in lhesleeve N, carrying the hand-wheel N This sleeve is provided with Ellimited number of screw-threads n", which engage in u screw-threadedcollar c, carried by the urn] C, last to the upper our rings (1. Byhuvin these scrmv-threads n not extending the Hill length of thescrewtlirends in the roller the sleeve may be moved longitudinnilthrough a limited disiztllCO only; but it will be obvious that thetin-ends o. boil: sleeve and collar mi ht he continuous. ii desired. Thesleeve N 1 provided with EU! annular groove n, into which project thepoints oi' the serous p, carried by the l)l()(,'l( l, in which block theshaft M is journuled. 'lhis hlorl; is provided with n guidvwziy 1/ (seeFig. (5) lo engage the flanges 0 so that the shalt 3i", :md with it theworm Rhinuy be moved toward or away lroin the wornugeur li' whendesired. Thus when ll!- sirod the num all the {ruining-grin" by turningthe hand-wheel N may throw the worm into or out of engagement. with theworm gear ii Vv hon it is de ired lo train flu un quickly, :1 quick inolion of the hund-wlwel hi by mechanical means only independent oi" theslioulder-har; but this bar may he used will cause the worm M lo bedrawn out of en- I the hand-Wheel N is turned in the reverse direction,causing the block P to move toward the shaft K, which will cause theworm M to engage .with the gear K at which time the training of the gunmay be etlected by means of the hand-wheel N which will rotate thepinion N and will turn the bevel-gear M and the worm M, causing thelatter to turn the pinion K, which will turn the upper carriage on thelower. Thus it will be seen that I have provided mechanism by means ofwhich the gun may be roughly and quickly trained, as from the shoulder,while extremely accurate training is effected by suitable powermechanism, and that I have also provided mechanism by which the line ofsight may be brought on the tar et and may be held there while the lineof me of the gun is brought into its proper relation with the lineofsight.

It will be seen that the gun-pointer can hold one hand on thetrigger-guard and with the other by manipulating the single Wheel F heis able to either change the angle between the line of fire and the lineof sight or may swing both line of fire and line of sightsimultaneously, as may be desired.

It will be evident that the sighting-arm'l) may be pivoted to any partof the top carriage, and the proportions of the same and the gearing foroperating the same might be so al- 'tered to correspond to such changeas to give the desired movement. This is a mechanical detail which maybe worked by any one skilled in the art.

It will be obvious that various modifications might be made in theherein-described apparatus which could be used without departing fromthe spirit of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-
